This compiles if you just declare the comparator functor's operator() before MyClass and you define it after the class definition like this: class MyClass; struct compare_distances { inline bool operator()(const MyClass* n1, const MyClass* n2) const; }; typedef boost::heap::fibonacci_heap<MyClass*, boost::heap::compare<compare_distances> > fib_heap; class MyClass { public: string name; double distance;...

Nodes with equal keys are OK. Recall the heap property: for min-heap, the key of each node is greater than or equal to the key of its parent. (The max-heap property can similarly defined.) A Fibonacci heap is just a collection of such trees. If more than one root has...

When erasing an element from a fibonacci heap, the tree is re-consolidated. As a general rule, when the amortized time of an operation on a fibonacci heap is O(log(N)), then tree consolidation is occuring. Conceptually, a Delete operation can be thought of as being the combination of two operations: For...
